LUBRlCATlNG-JOURNAL.

SPECIFICATION forming part of Letters Patent N 0. 258,655, dated May 30, 1882.

Application filed April 24, 1882.

To all whom it may concern Be it known that I, GEORGE KRATZ, a citizen of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in Lubricating-Journals; and I do hereby declare that the following is afull, clear, and exactdescription of the same, reference being bad to the annexed drawings, making a part of this specification, and to the letters and figures ot'reference marked thereon.

Figure l of the drawings is a sectional end view of my improved journal, having mounted thereon a spur-gear wheel; and Fig. 2, a sectional elevation thereof.

The present invention has relation to certain new and useful improvements in hollow lubricatirig-journals; and the object thereof is to avoid cutting out the gear-wheel that revolves on the same, as the entire wheel or wheels attached to a boiler of a portable engine become very hot, and consequently the oil runsout and burns up.

Theinventionconsistsin ajournal constructed substantiallyas shown in the drawings and hereinafter described.

In the accompanyingdrawings, A represents the journal, and B the spur-wheel mounted thereon.

The jourualA is formed hollow, or, in other words, with an oil-cup, G, into which is placed the tallow or raw lubricating material, said (No model.)

The oil-cup G has feed-holes b, so that when the heat from the boiler causes the lubricant in the cup to melt it will run through said openings onto the wearing-surface of both journal and wheel.

Having now fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

The combination, with a suitable spur or gear wheel and the side plate of a boiler, of the journal A, formed with oil-cup 0, having feed-holes b, and the annular flange 1) for securing it to the side plate, substantiallyas and for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

GEORGE KRATZ.
